Durable Truck Headache Rack: Protect Your Cab from Impact and Sun Damage

from

$249.99
For the heavy-duty hauler and hardworking trailer blazer, a headache rack is a must-have truck accessory. It does not take much for a two-by-four, steel pipe or other loose cargo to put a good size crack in the rear window of your truck cab, especially when you stick to the off-road trail more than the paved road. The ARIES classic headache rack offers a hardy design and sturdy structure to make sure your truck is ready to work. Made from 1″ x 2″ carbon steel tubing, ARIES classic headache racks provide excellent protection for your truck cab, from both the heat of the sun and potential impact from unsecure cargo in your truck bed. The full louvers help keep your cab cooler throughout the day, and their heavy-duty construction helps block any damage from behind. The ARIES classic headache rack also features a dual-layer E-coat and semi-gloss black powder coat finish to maintain its sleek appearance, preventing damage from rust, scratches and UV rays. Installation is quick and easy with the ARIES headache rack. It is compatible with cross-bed truck tool boxes and includes all necessary hardware for a complete installation. When your pickup truck is more than just a show horse, ARIES has you covered. We understand that it’s about more than goofing off in the mud. When you have a job to finish and a workhorse to drive, an ARIES classic headache rack is a reliable tool in your belt.

Product Features:
  • Heavy-duty 1″ x 2″ steel tube construction for a solid frame
  • Dual-layer E-coat and black powder coat finish for maximum corrosion resistance
  • Fully louvered center section to protect the cab and passengers
  • Louvers also help keep the cab cooler by blocking direct sunlight
